Hi,My family member just traveled from Asia to US. Since landing here 10 days ago, she has not been able to stay awake past 8 pm and gets up at 5 to 6 am. Sometimes she starts feeling asleep around 6 pm. This has been a very unusual jet lag. We have travelled many many times, but this has never happened before. She is in early 40's. The weather in US is also not co-operating. It's been extremely cold since she has landed. Any clues on what we could do? We will be seeing the doctor next week, but just wanted to check if there are any Over the counter things or other thing that she could do to get back into normal sleep cycle? Her normal bed time is around 10 to 11 pm.Thanks for your advice in advance.
